Product Procurement & Buyer Guide
Core Technical Specifications
The 1766-L32BXBA operates on a 24VDC external power supply. It provides twelve fast 24VDC inputs for high-speed counting. Eight normal 24VDC inputs handle standard signaling devices. The unit includes two analog voltage input channels. Its output section features six relay, three fast DC, and three normal DC channels. Two analog voltage output channels complete the I/O set. This controller supports up to six embedded 100 kHz high-speed counters.
Communication Capabilities
This model includes one isolated RS232/RS485 combo port. A second non-isolated RS232 port provides additional connectivity. One Ethernet port enables network integration and web server functions. Serial protocols include DH485, DF1, Modbus RTU, DNP3, and ASCII. Ethernet supports Ethernet/IP, DNP3, and Modbus TCP/IP. These ports connect to HMIs, SCADA systems, and third-party devices.
Memory and Expansion Options
The 1766-L32BXBA contains 20 KB of battery-backed RAM for user programs. A replaceable 1746-BA battery maintains data integrity during power loss. You can install up to seven 1762 expansion I/O modules. This scalability allows the system to grow with your application needs. The controller also features a built-in real-time clock for time-based control tasks.
Installation and Mounting Details
Mount this controller on a panel or DIN rail for flexible installation. Its open enclosure suits clean, dry industrial environments. The unit measures 3.5 x 7.08 x 3.43 inches and weighs 2 pounds. Use it with circuits not exceeding Over Voltage Category II. The operating frequency range spans 47 to 63 Hz. Power supply inrush current reaches 15 A for 20 ms at 24V DC.
Application Engineering Insights
Procurement managers value the 1766-L32BXBA for its cost-effective I/O integration. Application engineers benefit from its mixed input and output types. The fast DC inputs handle high-speed counting up to 100 kHz. Relay outputs switch loads from 5 to 125V DC or 5 to 264V AC. Analog I/O channels accept 0 to 10.0VDC signals with 12-bit resolution. This versatility reduces the need for additional specialized modules.
Compatibility with Memory Module
The 1766-L32BXBA works seamlessly with the 1766-MM1 memory module. This accessory provides 384 KB of additional storage for program backup. It prevents data corruption from voltage surges or human error. The module supports hot insertion and removal under power. Program compare and write protection features enhance operational security. This combination ensures maximum uptime for critical processes.
